STEAM PURIFIER.

Application filed December 4, 1925. Serial No. 73,278.

This invention relates to purifiers or separators, more particularly for drying, cleaning, and purifying steam, gases, or vapors, but as a leading use the purification of steam issuing from boilers.

The drying or cleaning of steam and vapor V the outlets of steam boilers and evaporators has heretofore presented problems which have been difficult of solution. present invention relates to that type of apparatus for cleansing or purifying steam of entrained moisture and solids in which a plurality of gutters, channels, or channellike battles are used to intercept the moisture and solids and return them to the boiler, or evaporator, while the purified or cleansed steam escapes fr om the apparatus in a truly dried and purified condition.

In the drawings, which illustrate two forms of the invention,

Fig. 1 is a view in perspective of one form of apparatus, with certain portions broken away;

Fig. 2 illustrates the upper portion of a boiler with the apparatus installed at the steam discharge nozzle thereof, partsbeing in longitudinal section;

Fig. 3 is a sectional view showing the typical arrangement of upright grooves or channels for intercepting and collecting the globules of water, oil, or other heavier substances;

Referring to Fig. l, the apparatus comprises a box or top 3, which may be of suitable sheet metal and is provided with closed ends 4, and downwardly inclined or sloping side portions 6. are composed of suitable numbers of grooved or channel members 7, which extend from the top 3, which closes their upper ends, downwardly at an inclination, with their open sides facing outwardly. The grooved channel members 7 in the second row are staggered with reference to those in the first row, and the same arrangement will exist in any subsequent rows regardless of their number, whereby the spaces between the channel members of any layer are opposite the central portions of the bodies of'the channel members of the preceding row.

At a central point, and extending longitudinally of the body of the apparatus, is a plate 8 against which the lower ends of the channel members 7 abut, so that as the steam impinges against the various channel mem- The The sloping side portions.

In Fig. 2 of the drawings, the apparatus is shown in side elevation, with its discharge connected with the steam nozzle 10 of the boiler, so as to represent the position thatthe apparatus occupies in the boiler when in use.

A characteristic of the invention is based upon the fact which I have discovered by experiment that the globules of water taken out of the steam during its passage through a multiplicity of collecting surfaces like the.

channel members 7, will escape downwardly through the action of gravity and back into the boiler against the steam pressure in the boiler. very simple apparatus, with a free and open discharge from each of the moisture collecting elements or surfaces, and without resorting to a closed pan, or receptacle, for collecting the separated moisture, with a dis charge. pipe therefrom leading outside of said boiler and away from its pressure. As before stated, this is a very important feature of the invention, and has enabled me to produce a very simple apparatus which is highly eiiicient in operation.

Having thus described my invention, what I claim as new and desire to secure by U. S. Letters Patent is 1. An apparatus of the class described comprising, in combination, a top, a purified fluid conduit leading from said top, downwardly inclinedsides composed each of a plurality of rows of outwardly facing channel members, a central vertically arranged plate or member extending longitudinally of the apparatus, said channel members having their lower ends opening against said plate for discharging and directing downwardly the water and other impurities which have been separated from the fluid.

2. An apparatus of the class described comprising, in combination, a top member, a discharge conduit for dry steam therefrom, side members composed of pluralities of This fact enables me to employ a layers of open channel members, adjacent against said plate, whereby the moisture exlayers of members being staggered with re'ftraeted from the steam in passing through 10 erence to other members, end members, and said channel members is discharged freely a central vertically arranged holding and downwardly into the boiler.

directing plate extending longitudinally of In testimony whereof Ijhave hereunto set the apparatus at the lowermost point of my hand this 2nd day of December, A. D. meeting of the downwardly extending ehan- 1925. V nel members, said members discharging CHARLES GILBERT HAWLEY.
